Hi, Wow, that's an exciting service, please leave your contact details, and we can all immediately call, as we are desperate for electro-mechancial design modeling and simulation services for all our feeders. I was just thinking about electro-mechan

Hello! I have a strage problem, we made some production with uBGA, BGA, 0201, 0805, and other type of component. We didn't put the uBGA and 0201 and BGA on the board at the end of the line we look a our solder joint and surprise the solder made a

The camera is important. I found the only machine, granted this was a year ago, capable enough for volume production, was the KME CM-88. Our test had 1 mispicked device of 5,000,000 attemps and 0 misplacements.

Yes your CP8 should place these flawlessly. I would calibrate the machine and check your nozzles. We have some CP7's and they rock. We use a .4 nozzle for the 0201's with no problem. Always check your program, feeder, nozzles, and nozzle check before

Dave- Excuse the shameless self promotion but we market a product that does just what you are referring to...measuring Cp and Cpk levels on SMT equipment. If you've ever had the desire or need to gather this data on your in-house SMT equipment pleas

Hello bphillips, I'm not surprised you're having difficulties with this size chip. As technology advances in product development continue to shrink package and real-estate size, the equipment and its automation must continue to perform it's desired f

Hi John, I don't know if you are going to have a lot of luck obtaining this information. Currently 0201's are mostly used in Asia, and reliability issues have risen using these components. The problem is obtaining a reliable solder connection with a

Challenges: The basic defects that impact assembly yield are bridging, satellite solder balls, and opens (i.e. tombstones / draw bridges). There are many variables with the stencil printing process that can impact these; several of them are listed

We have been placing 0201 in our production using both CP642 and CP643 since last year. But it was necessary to upgraded a narrow view camera to recognize 0201 for CP642. Since then, the placement of 0201 is really reliable.

In the true sense of the term, tombstoning can only occur during reflow. Now, if your solder joints are cracking during thermal cycling and opening on one end you still have a problem - it just isn't "tombstoning". What laminate are you using on yo
